If the service is paid, there must be industrial and commercial registration first. Of course, diving clubs must have coaches, divers, offices, training places (swimming pools), boats, diving equipment, air compressors and so on. Domestic divers should go to China Diving Association for the record, and they will tell you the specific personnel qualification requirements (several coaches, divers, etc.). ).
It's cheaper to go to Thailand or the Philippines to take the coach's certificate, about 30 thousand RMB, for half a year. The domestic exam may be 50,000-60,000.
